  • Publication number: 20230107555
    Abstract: A facial expression editing method includes obtaining a to-be-edited image, where the to-be-edited image includes a first face image of a user; obtaining, by using a camera, a first video stream including a second face image of the user; editing the first face image of the user in the to-be-edited image based on the second face image of the user in the first video stream to obtain an edited image, where a facial expression of the user in the edited image is associated with a facial expression of the user in the first video stream.

  • Patent number: 7340267
    Abstract: In a system having a base station transmitter for transmitting data blocks to one or more mobile stations over a radio link, there is a method for determining an uplink transmit power level at which to transmit a current data block over a radio link from the mobile to the base transmitter station. The method evaluates airlink quality measurements in the radio link over a measurement interval, wherein each time a message is sent to the mobile station, it is evaluated whether a specified number of uplink blocks have been transmitted by the mobile station since the start of the measurement interval. Based on the evaluated airlink quality measurement, the method determines the uplink transmit power level that the mobile should be using for the current block, and adjusts the transmit power level, if necessary, for the current block.

  • Patent number: 7313092
    Abstract: The present invention is a methodology to prioritize packets based on the conditional probability that given the values of attributes carried by packet, the packet is a legitimate one. We will call this the conditional legitimate probability of a packet from here onward. The conditional probability of each packet is evaluated based on Bayesian estimation technique. This is accomplished by comparing the attributes carried by an incoming packet against the “nominal” distribution of attributes of legitimate packet stream. Since an exact prioritization of packets based on their conditional legitimate probability would require offline, multiple-pass operations, e.g. sorting, we take the following alternative approach to realize an online, one-pass selectively dropping scheme.
